Specification 01' Letters Patent.

Patented May 2, 1916.

Application filed June 9, 1914. Serial No. 843,938.

To all whom it may concern:

Be it known that we, OonNnLms F. DoNo- VAN and JOHN P. DONOVAN, citizensof the United States of America, and residents of Westfield, in thecounty of Hampden and State of Massachusetts, have invented certain newand useful Improvements in Whip- Oenters, of which the following is afull, clear, and exact description.

The object of this invention is to provide an improved construction of awhip center, that is to receive the usual outer coverings to form thecomplete article, that will possess the desired and requisite amount ofelasticity, and yet will insure great durability in the article.

A further object of the invention is to provide such a device in whichthe winding will not result in the formation of channels or depressionsafter it becomes set or fixed on the core. a

In the accompanying one embodiment of our invention,Figure 1 shows apartial length view of the center in elevation; Fig. 2 shows a similarlength of the core; Fig. 3 is a similar view of a modification; Fig. Ashows a front elevation, and Fig. 5 shows a side elevation of thewinding strip and Fig. 6 is a cross section on the line 8-8 of Fig. 4.

In the drawings we show a core 10 formed of a rod that is very slightlytapered throughout its length, and which is cular cross section; the rodbeing formed of spring steel of a high grade. On this rod we place acovering, by taking a strip 13 of raw hide, and wind it spirally aroundthe rod with the edges adjacent as indicated in the drawings. The rawhide strip is preferably first moistened or saturated. with water andthen spirally wound on the core, so that when the strip becomes dry, itwill shrink onto the core and become firmly fixed or set thereon. Thestrip of raw hide is preferably reduced at its edges or skived, asindicated in Fig. 6; and this form of strip is wound spirally on thecore 10 preferably with the comparatively thin edges slightly,

- in its wet or saturated condition, and becomes fixed or set thereon bydrying, the shrinkage that will reduce the width of the topics or thispatent may be obtained for five cents each, by addressing the Co ofcirstrip, will still leave overlapping edges, and, therefore, there willbe no channels or recesses formed in the device.

In the use of the whip, when it becomes slightly bent by reason of itselasticity, the small amount of movement of the overlapping edges of theraw hide will not produce channels or depressions, partly by reason ofthe material being lapped; and partly be cause of the pliability orslight degree of extension of the comparatively thin lapping edgeportions; and which edges being brought together while wet will have acertain amount of adhesion that will hold them together.

l Ve claim 1. A whip center composed of a core of a slightly taperedspring steel rod of circular cross section, and a covering on the coreformed of a strip of raw hide of gradually I reduced thickness from itslongitudinal drawing, showing center to its side edges, said stripspirally wound on the core.

:2. A whip center composed of a core of a slightly tapered spring steelrod of circular cross section, and a covering on the core formed of astrip of raw hide that has its side edges reduced or skived, the stripbeing spirally wound on the core with the edges slightly overlapping.

3. A whip center composed of a core of a slightly tapered spring steelrod of circular cross section, and a covering on the core formed byspirally winding thereon a strip of raw hide of non-uniform thicknesstransversely in its wet condition to become set thereon by its shrinkageon the core.

4. A whip center composed of a core of a slightly tapered spring steelrod of circular cross section, and a covering on the core formed byspirally winding thereon a strip of raw hide that has its side edgesskived and which is wound on the core in its wet condition to become setthereon by its shrinkage on the core.
